http://www.shiply.com/For those of you who send parts or want to buy cars miles away from you this site might be of some help.
If you look at the search shipments area you can get an idea of the kind of prices things are getting shipped for. Basicly you post up what you want taken and the to and from addreses and couriers bid on the job.
Obviously its not just for car related things and its not for everybody but i thought it may be of some use to some of you.
